CUSHIONED CARTON Filed June 21, 1928 2 Sheets-Sheet 2 Patented June 24, 1930 1 UNITED STATES PATENT: OFFICE I I'ELIZ TROYK, OI" CEIGAGO, ILLINOIS, ASSIGNOR TO SELF LOCKING CARTON COH- PANY, A CORPORATION 01 ILLINOIS C'U'QHIONED CARTON I Application filed June 21,

The resent invention relates to cartons .for pac aging fragile articles, particularly eggs, and has for its object to produce a simple and novel carton requirin a minimum amount of material and I a apted to house a plurality of such articles. and provide effective cushioning supports for the same.

A common form of egg carton is one in which eggs, usually a dozen, are housed in individual compartments arranged in two rows lying side byside. Viewed in one of its aspects, the resent invention may be said to have for its 0 ject to produce from a sin 1e 16 blank a carton in which eggs or other artic es may be housed in individual compartments arranged in parallel rows, and at the same time be efir'ectlvely cushioned.

The various features of novelty whereby m invention is characterized will hereina er be ointe'd out with particularity in the claims; ut, for a full understanding of my invention and of its objects and advantages, reference may be had to the following de tailed description taken in connection with the accompanying drawings, wherein:

Figure 1 is a vle'w of my improved blank in a flattened condition; Fi 2 is a front view, on a larger scale; of a agment of the completed carton in a closed condition; Fig. 3 is a top plan View of the carton, on a larger scale than Fig. 1 and a smaller scale than Fig. 2, showing the cover open and two eggs in position in the carton; Fig. 4 is a section on the same scale as Fig. 2, taken ap roximately on line 4-4 of Fig. 3, the cover eing shown in its closed position; and Fig. 5 is a section on the same scale as Fig- 4 taken approximately on line 55 of Fig. 1, the cover being shown closed.

The blank, of cardboard or any usual or suitable carton material, comprises six main sections, arranged one beside the other,and two narrow terminal sections. The first main section 1 forms the cover; the next section 2 is adapted to form one of the sides; the next two sections, 3 and 4 are ada ted to form the bottom; the fifth section 5 is adapted to form the front side; and the sixth sectlon 6 is 50 adapted to form the transverse partitions and 1 vided with hooks 8. At

locking stri blank, the blank is folded alon HEISSUED 1528. Serial No. 207,335.

to connect the upper arts of the front and rear sides together. 11 the free long? edge of the cover section is a locking strip prothe opposite end of the blank, following the section 6, is a narrow attaching strip 9.

The blank is scored along parallel lines, indicated at 10, to mark the dividing lines between the several sections including the and the attaching strip.

Each of t e two bottom sections, 3 and 4, is provided wit slots 11 spaced apart from each other and arranged parallel with the long edges of the b1ank;'there being one more slot in each section than there are to be compartments in one of the two rows in the completed carton. Each slot in one of the bottom sections is in line with the corresponding slot in the other section. Furthermore, if the carton is to be used for packaging eggs or similar articles, each bottom section is provided with comparatively large holes 12 alternating with the slots.

The section 6 is cut up into partially sev-- ered flaps 13, there being as many flags as there are slots in each bottom section. ach flap is joined to the front wall or side member 5 at one end and also to the attaching strip 9 at the corresponding end; this end being the portion of the. flap which is at the top when the carton is set up and the flaps are turned down to produce transverse partitions. Each flap decreases gradually in width from its attached end to its free end, and a deep notch is cut out of the free end at, the middle. This notch increases abruptly in width so as to form a central V-shaped opening 14 facing which are shoulders 15 outwardly from the V-shaped part. In other Words, each flap may be said to be forked, C

that is composed of a cross-piece having on opposite sides tapered prongs or legs provided with hook elements on their inner sides or edges. In cutting out the legs of one flap there is left a lateral projection 16 on the adjacent end of the next succeeding flap.

In producing a carton from my improved the scored lines, excepting the scored line etween the two bottom sections, the folding being always in the same direction with respect to the original plane of the blank, and being continued until each section, including the end strips, is approximately at right angles to each of the adjacent-sections; excepting only that a fold is made. between the two bottom sections so as to make them stand at an angle to each other and appear-as an inverted V in end elevation. Suitable adhesive being applied to the attaching strip 9, it will be found that this strip, as shown in Figs. 4 and 5, will engage with the rear wall section 2 at some distance from the division line between this section and the cover section. When the attaching strip is properly pressed against the rear wall or side section 2 and the adhesive caused to set, it will be found that the section 6, with its flaps still in their original plane, will lie horizontal when the carton is set on a flat surface. When the flaps are turned down, as shown in Figs. 3, 4 and 5, the legs of each flap will pass through the corresponding slots in the two inclined bottom sections, as best shown in Fig. 5; the shoulders 15 projecting into the inverted valley underneath the carton, while the V-shaped notches 14 fit over the meeting bottom wall sections at their intersection. The flaps are made long enough so that, when turned down, their lowermost points will rest on a fiat surface upon which the carton is set.

When eggs, of which two are indicated at A in Figs. 3 and 4, are placed in the carton, each will be in its own individual compartment bounded on two sides by the transverse partitions; the compartments in one row being separated from those in the other row by a central partition, shallower than the depth of the box, formed by the inverted V-shaped bottom wall. Each egg may project partially through the underlying hole 12 in the underlying bottom section; these holes permitting articles of larger dimensions to enterthe V-shaped bottoms of the compartments than would be the case if the holes were 'not there.

When the transverse partitions are swung down, the only porti Tns of the section 6 that remain in the normal plane are the triangular pieces 17 at the front and at the back,

5 which triangularpieces form the connections between the transverse partitions and the front and rear wall of the carton. In closing the carton, the cover is folded down and the hooks 8 on the locking strip along the free edge of the cover are engaged with the triangular pieces 17 along the "front of the carton in the usual way.

It will be seen that when the carton is closed the projections 16 at the centers of the transverse partitions engage with the underside of,the cover so as to prevent the latter from being pressed down and crush the eggs. In other words, the cover is supported at its long edges by the front and rear walls particularity of the carton and along the longitudinal center by the transverse partitions.

Ordinarily the cartons will be shipped in a.

horizontal then, by folding the partition section 6 on a longitudinal center line, the shell or body portion of the carton may be laid flat. In the flattened condition, the two halves of the partition section overlie each other as'do the two halves of the bottom section, while the section 4 overlies the section 3 and the front wall section 5 overlies the rear wall section 2. In orderto facilitate the collapsing of the carton into its flattened condition, I prefer to score the partition section 6 along the longitudinal center line, as indicated by the broken line 18. i

It will thus be seen that I have produced a simple and novel multiple compartment carton in which the compartments are arranged in two rows side by side; the carton being made from a 'singleblank; and the construction being such that the contents are effectively cushioned from below, while the carton is structurally strong to resist compression when aweight is placed upon the same. Consequently the carton will cost no more to make than does the ordinary uncushioned carton with the same number of compartments, while the contents are better protected against breakage than they are in an 0rd1 nary carton.

While I have illustrated and described with only a single preferred form of my invention, I do not desire to be limited to the exact structural details thus illustrated and described; but intend to cover all forms appended claims.
